一、卫星电视地面接收站有什么用处? 同步卫星位于地球赤道平面上空35786公里(约36000公里),犹如一座36000公里高的发射天线,所以在收不到电视节目的边远山区、林区等,通过卫星电视接收站,便可直接接收到从36000公里上空发来的电视节目。而对于所经的传输环节多,收看质量不好的地方,则通过自己建立地面接收站,可直接收节目,从而排除中间环节的种种干扰,获得良好图象。二、卫星电视地面接收站,包括哪些基本设备? 一般成套卫星电视地面
I. What is the use of the satellite television ground receiving station? The synchronous satellite is located 35786 kilometers above the Earth’s equatorial plane (about 36000 kilometers), like a transmitting antenna with a height of 36000 kilometers. Therefore, in remote mountainous areas and forest areas that do not receive television programs, Through the satellite television receiving station, you can directly receive over 36,000 kilometers from the television program. As for the transmission link, and watch the place where the quality is not good, then through their own establishment of the ground receiving station, you can receive the program directly, thus eliminating the interference of the intermediate links, get a good image. Second, the satellite television ground receiving station, including the basic equipment? General satellite television ground
